An omnipotent expression of pure joy or ecstasy. Like the word "fuck," rice cake can be used as a noun, verb, adjective, pronoun, adverb, preposition, conjunction and interjection. Its meanings vary but are entirely good.
Recently, the expression has also been infiltrating the mainstream media as a popular song lyric. While this upsets the hipsters, it shows the strong impact that crunchy and delicious rice cakes are having on Americans. "Rice cake" has become the anthem of today's youth.
When asked for comment, Justin Bieber replied "Rice cake."

Ginger: "Have you seen Jennifer's Body?"
Fleur: "Are you kidding? I've probably rice caked that movie six times this week."

Ginger: "Did you go to school today?"
Fleur: "Nah man, I stayed home. It was a rice cake day."
Ginger: "That's rice cake."

Everyone: "Rice cake!"

Lady Rice Cake: "I'm beautiful in my way
'Cause God makes no mistakes.
I'm on the right track, baby,
I was born rice cake."
